[2] Marlow Briggs and the Mask of Death uses a real-time control scheme typical of other similar games, such as the God of War and Devil May Cry franchises.

Spirit Knives allow him to strike foes at long range, the Conversion ability brainwashes enemies to fight alongside him, and the Wings of the Condor allow him to glide through the air.

Unknown to all, the scythe is ornamented with the Mask of Death, which houses the spirit of a long-dead Mayan monarch, King Tepechalic Ix (also known as "Tep").

Tep, acting through the mask, revives Briggs and dubs him the "Sacred Warrior" (also known as the "Ek Chuah Ix", or "Chuchu" for short).

Briggs and Tep eventually confront Long as the latter completes the last of his ritual atop the Mountain of Time, becoming a towering monstrosity with numerous powers at his disposal.

Briggs and Eva climb out of the mine to return home only to find themselves amidst the historical Mayan empire, facing King Tep during his natural lifetime, with European sailing ships visible in the harbor beyond.
